Himalayan tahr control operations: Tahr

DOC is working with Ngāi Tahu and the Tahr Plan Implementation Liaison Group, to achieve the goals of the Himalayan Tahr Control Plan 1993.

Each year, we work with hunting, conservation, recreation, and land management stakeholders to produce an operational plan. We do this through the Tahr Plan Implementation Liaison Group (TPILG), which includes numerous stakeholders with an interest in tahr, including hunting, outdoor and conservation groups.

The annual plan outlines how DOC will work in partnership with various groups to control tahr and protect native ecosystems. This includes on and off public conservation land.

Operational Plan 2023/24

This plan will conclude on 30 June 2024, to be replaced by the 2024/25 operational plan. At the date of update (14 June 2024), a small amount of official aerial control outside the tahr feral range is the only work remaining under this plan.

Operational Plan 2024/25

This plan was developed through engagement with the TPILG over 5 months. Their feedback from meetings and in written submissions helped to refine this plan, which will commence on 1 July 2024 and last until 30 June 2025.

Updates throughout operations

Updates regarding operational progress will be provided throughout the period of the operational plan. In particular, DOC will communicate when official aerial control is concluded within a Management Unit. This gives hunters and other recreational users certainty that they won’t encounter a control operation while recreating.

Updates will be via this web page and emails to hunting permit holders.

Maps showing control and bull tahr locations

Maps showing where official aerial control of tahr was undertaken, and where identifiable males were spotted and left for hunters, are available on the tahr sightings and control maps page. Typically, this mapping page will be updated periodically between July and December, as official aerial control operations conclude within an area or Management Unit.

Aim of the control plan

DOC’s Tahr Control Operations are guided by the statutory Himalayan Thar Control Plan 1993. This was developed under section 5(1)(d) of the Wild Animal Control Act 1977.

The plan sets a maximum population of 10,000 tahr across 706,000 ha of private land, Crown pastoral leases and public conservation land within the tahr feral range. The feral range is the legal boundary of where tahr are allowed to be.

Different control approaches ‘at place’

The control plan details the work we have planned for the year; the amount and location of control effort may change as/if new information becomes available during the operational period. A summary of our plans for some places is available below.

Around the midpoint of the control programme DOC and the Game Animal Council will meet to review the work undertaken. Discussions from that meeting will informed management decisions made for the remainder of the plan period.

Our focus on outside the feral range and national parks

This plan focuses most effort on controlling tahr outside their feral range, with some complementary work outside management units but within the feral range, to prevent tahr spreading into new areas. Substantial effort is also allocated to tahr control in national parks, to protect these special places.

Hunter-led management for South Rakaia/Rangitata (Management Unit 1)

DOC is supporting the New Zealand Tahr Foundation, with assistance from the Game Animal Council and in partnership with Te Rūnanga o Arowhenua, to develop a plan for hunter-led management of the South Rakaia/Rangitata (MU1).

The scope of hunter-led management and the activities it encompasses are still being developed but could involve hunters managing tahr populations, documenting the number of tahr controlled by hunters and reporting on and the health of ecosystems. DOC is excited to see what can be achieved by working together with the group on this opportunity.

Work in other management units

Within other management units, effort within this plan will focus most effort on places which are difficult for recreational hunters to access, but where tahr numbers and/or impacts are high.

We will not target identifiable male tahr over the 425,000 hectares of public conservation lands inside the feral range, outside national parks.

Official control of tahr conducted by aerial hunting will focus on winter and early spring to maximise control efficiency and minimise conflict with recreational users, including hunters.

In 2024/25 year we will also use professional ground hunters and targeted management hunts conducted by hunting groups to control tahr, particularly in forest areas where animals can be hard to spot from the air. These hunts will occur in spring, before the peak in kidding, and in late summer/early Autumn, before the rut.

New research to support our planning

DOC’s research and monitoring programme is continuing this year with several initiatives underway to learn more about the tahr population and ecosystems.

We will conclude analysis of data from the remeasurement of historic vegetation plots and from a recent pilot of a more ‘rapid’ method to understand tahr impacts on vegetation condition. The results of those analyses will inform further monitoring and operational delivery, within the 2024/25 plan, and beyond.

In early 2023 a series of aerial surveys were undertaken to inform a new estimate of the tahr population on public conservation land across the management units. The results from that survey are available below, and on tahr and conservation page along with other research and monitoring information relating to tahr. We plan to further develop our understanding of tahr populations in 2024/25 through the scoping and piloting of a demographic population model for tahr.
